Attiny13A sleep mode
Attiny : arduino's little brother Arduino is a very good card but if you need a very smaller card size or if you don't need alls pins and less memory, Attiny is a good alternative VCC =Voltage is 2.7-5.5 v Notice : Pins output high voltage is 4.3 volts with a Vcc of 5 volts. For 3.3 Vcc, pins o utput voltage is 2.5 V So be carefull, this is not 3.3 volts like Arduino How to program Attiny To program attiny, just use Arduino IDE. To do this, you will have to connevt Attiny to arduino. Arduino will now be used as bridge Initial step Upload ArduinoISP sketch on your arduino : Select card Arduino Uno Load sketch Samples > 11.ArduinoISP Tips : be sure to unplug all wires before to upload the sketch First step First time and only once, you have to write bootloader on Attiny : Choose 'Arduino as ISP' as the programmer prior to burning the Arduino bootloader onto the ATtiny Select card ATtinyXX Verify Board Properties...
